|Denon makes one of, if not thebest line of sealed headphones. This noise cancelling stuff is tricky though, and the Denon AH-NC732K is about $100 less expensive than any of the other headphones in this test, so it had a tough time keeping up with the rest of the pack. Like the Sennheiser PXC 450 on the previous page, the Denon runs on a single AAA battery for about 40 hours and can operate as a passive headphone. So if you do run out of juice you you can still keep playing your music, and the batteries are easy to find. These are the smallest headphones we tested in this series, and as a result have the smallest carry case and are easiest to transport. They also rest on your ears (rather than encircling them) and are slightly less comfortable than the other cans as a result.|
|[caption id="" align="alignleft" width="251" caption="Frequency response data for the Denon AH-NC732K"] [/caption]The sound quality of these little cans is a bit disappointing. There's a bit of a suck-out in the lower mids, and the very high frequencies have gone missing. On the other hand, the bass is fairly solid and kickin', and the bump up at 1-2kHz gives them a little boost in speech intelligibility. So, the sound is a bit uneven, though still quite listenable.These are also the least expensive of the cans reviewed here by a pretty wide margin, so some of their weaknesses can be forgiven in light of the company they are keeping here. Their low price, small size, and long battery life make them a solid choice for someone who spends a lot of time in the air on long flights --- especially if you're into movie watching.|
